Frequently Asked Questions
- Does this blur only the background?
- This simple version blurs the entire image uniformly. For subject-only blurring, an AI segmentation tool would be needed — this is a browser-side solution.
- What blur amount should I use?
- 5–8 for subtle softening, 10–15 for noticeable blur, 16–20 for heavy abstraction. Start low and increase until you like the result.
- What file formats are supported?
- JPG, PNG, WebP, and GIF. The output is always PNG to preserve quality after the blur filter is applied.
- Is the image uploaded to a server?
- No. The blur is applied entirely in your browser using the Canvas API. Nothing leaves your machine.
- Can I use this on video frames?
- Not directly — this tool processes still images only. Extract frames from video first, then blur each individually.
- Does blur reduce image quality?
- The Gaussian filter does not degrade resolution, but the output is re-encoded as PNG. Start from the highest-quality source for best results.
